4. Test the Charging System:

  • Multimeter Check: With the engine running, check the voltage at the battery terminals again. It should read between 13.5 and 14.5 volts. A lower reading indicates a problem in the charging system. This test checks both the alternator and the wiring between the alternator and the battery.

5. Consider the Battery's Age:

  • Battery Lifespan: Car batteries typically last 3-5 years. If your battery is nearing the end of its lifespan, it might simply be time for a replacement.

6. Investigate the Wiring:

  • Damaged Wires: Inspect the wires connecting the battery to the alternator and the rest of the electrical system for any breaks, fraying, or loose connections. Repair or replace damaged wires as needed.

7. Consult a Professional:

If you've followed these steps and your car battery still won't charge, it's best to take your vehicle to a qualified mechanic for a proper diagnosis. They have the tools and expertise to pinpoint the exact problem and provide the necessary repairs or replacement.

Simple Answer: Check battery terminals for corrosion and tightness, test battery voltage, and have the alternator tested. If problems persist, see a mechanic.

Casual Reddit Style: Dude, my car battery's dead AF. First, check the terminals for that crusty white stuff – clean that junk! Then, get a multimeter and test the voltage (should be around 12.6V). If it's low and the alternator's acting sus, take it to a shop. It's probably either the battery or the alternator. Don't forget to check the cables too. Could be a bad connection. Could be your battery's just done.
